Im nearing the completion of my rebuild ( thank god )
Now im giving what oil to use in it some thought...
I used to use Quantum syntha gold as both audi and JBS auto designs recomended,
But now VAG have seen fit to use the platinum oil instead which im not sure is the best for the job.
With it being a new engine i would like to start off in the right way.
Some people also say use running in oil. some say use some minarel oil such as castrol gtx for a couple of hundred miles then drop it and swap to what you plan to run the engine on full time.

Any view??
 
What ever you do DO NOT run an engine in with synthetic oil. It's way too slippery and the rings will not bed in. You'll have to strip down the engine again and re-hone the bores.
You have had the bores honed for new rings.....correct?

Most of the running in is done in the first few miles. You want to get the engine up to temp and drive about for a bit. Then dump the first oil and filter after those first few miles. Then another dose of mineral oil for another 100. After that, you can use whatever you like.
